Purge everything
To maintain optimal site performance, Cloudflare strongly recommends using single-file (by URL) purging instead of a complete cache purge.
Purging everything instantly clears all resources from your CDN cache in all Cloudflare data centers. Each new request for a purged resource returns to your origin server to validate the resource. If Cloudflare cannot validate the resource, Cloudflare fetches the latest version from the origin server and replaces the cached version. When a site with heavy traffic contains a lot of assets, requests to your origin server can increase substantially and result in slow site performance.
- Log in to your Cloudflare dashboard ↗, and select your account and domain.
- Select Caching > Configuration.
- Under Purge Cache, select Purge Everything. A warning window appears.
- If you agree, select Purge Everything.
Purge Everything invalidates the resource, resulting in the CF-Cache-Status header indicating EXPIRED for subsequent requests.
